Abstract
To provide a stator capable of achieving downsizing and high output power and a stator manufacturing method, a stator comprises a split stator core and slots formed between the teeth, and protrusion-formed coils each being made of a flat rectangular conductor and placed in the slots. Each protrusion-formed coil has a shape including, in a coil end portion, a lead-side protrusion or a non-lead-side protrusion formed to protrude upward in an axial direction of the stator core from a first oblique side portion, a second oblique side portion, a third oblique side portion, and a fourth oblique side portion, and a first oblique side portion, a second oblique side portion, a third oblique side portion, and a fourth oblique side portion. The lead-side protrusion or the non-lead-side protrusion is designed with a height to avoid interference between the protrusion-formed coils placed in the stator core.
